A class of 2-aryl-4-aminoquinazoline derivatives (7a-7j, 8a-8h, 9a-9h and 10a-10k) were designed, synthesized and evaluated as EGFR inhibitors. The anti-proliferative activity of compounds in vitro showed that compound 9e was considered to be a promising derivative. Compared with the lead compound Angew2017-7634-1, 9e exhibited excellent inhibitory activity against A549, NCI-H460 and H1975 cell lines
设计、合成和评估了一类 2-芳基-4-氨基喹唑啉衍生物(7a-7j、8a-8h、9a-9h和10a-10k)作为 EGFR 抑制剂。化合物的体外抗增殖活性表明,化合物9e被认为是一种很有前景的衍生物。与引线化合物相比Angew2017-7634 - 1,图9e显示出优异的抑制活性对A549,NCI-H460和H1975细胞系,用IC 50个14.33±1.16μM的值,17.81±1.25μM分别和13.41±1.14μM。此外,9e能有效抑制 Ba/F3-EGFRDel19/T790M/C797S细胞系。在激酶实验中,最有前景的化合物9e对EGFR L858R/T790M表现出优异的酶抑制活性和选择性,IC 50值为0.74 μM。进一步的活性研究表明,9e不仅可以诱导 A549 显着的细胞凋亡,而且可以以浓度依赖性方式阻断 S 期的 A549 细胞系。此外,分子对接研究揭示了9e的
